Vibration Monitoring Unit Type HE250
The HE250 type vibration monitoring unit is used to measure and monitor absolute bearing
vibrations in machines in line with DIN ISO 10816. Furthermore, vibration monitoring determines
a bearing status parameter for the roller bearing diagnostic.
It offers the following features:
•
Two limit values and associated delay timings can be adjusted separately.
•
The two relay outputs will signal any exceeding of the relevant defined limit values. This
can be used to generate a pre-alarm and a main alarm.
•
Measurement parameter: The effective value (rms) of the vibration velocity (mm/s).
•
Analogue current output: Interference-free DC signal from 4-20 mA, proportional to the
measuring range of the monitoring unit.
•
Analogue current output: Interference-free DC signal from 4-20 mA, bearing status

Intended Use
Type HE250 is used to protect machines and mechanical equipment against undue strong
vibrations. Its use is only permissible within the specifications stated in the data sheet. It is used
exclusively for measuring mechanical vibrations.
Main fields of application:
Fans, ventilators,
blowers, electric motors, pumps, centrifuges, separators, generators, turbines and similar
oscillating mechanical equipment.
If the equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.
